Recently, the Ministry of Industry and Information Technology of China and the General Administration of Quality Supervision, Inspection and Quarantine released the National Motor Energy Efficiency Improvement Plan (2013-2015), which is expected to drive the market demand for nearly 100 billion yuan of high-efficiency motors and related equipment.

The promotion of high-efficiency motors can be traced back to 2008. From 2008, China's motor system energy conservation was listed as one of the top ten national energy conservation projects in 2008. In 2009, the application of high efficiency and ultra-high efficiency motors was included in the Huimin project. 6 A notice was issued on the 2nd of the month that high-efficiency motors were included in the implementation of energy-saving products and Huimin projects, and the market promotion of high-efficiency motors attracted much attention. It can be seen that it has been five years since the country entered the market for high-efficiency motors. However, high-efficiency motors are not fully integrated into the market.

According to experts, high-efficiency motors can save 1300-230 billion kWh of electricity, which is equivalent to 3 Three Gorges power stations. Why is it so difficult to become a high-quality motor edge in the hands of the user?

The high cost of high-efficiency motors and the unfavorable market conditions have resulted in fewer manufacturers, causing users to have insufficient awareness of high-efficiency motors. This is one of the main reasons.

Wu Ruiyang, general manager of Fujian Hesheng Energy-saving Technology Co., Ltd., said that motor sales face three types of customers, namely end users, agents and equipment suppliers. The proportion of its product consumption is respectively 5% for end users and 15% for agents, and 80% for downstream machinery and equipment suppliers. It can be seen that whether high-efficiency motors can be accepted by the market eventually and machinery equipment suppliers The attitude is the most critical.

Due to high R&D investment and high manufacturing costs, the price of high-efficiency and energy-saving motors stays high, the market price is 20% higher than that of ordinary motors, and some even exceed 50%, leading many investors to generate the idea of ​​“energy saving and not saving money”. Motors are generally used as backbone products, and are mainly used for supporting such main engines as fans, pumps, and compressors. Most of the host companies and construction projects of mechanical equipment suppliers are not final use. Zhou Shou Lian, chief engineer of Beijing Bijie Electric Plant, said that although high-efficiency motors The price is slightly higher, but as long as the running time is higher than 4,000 to 5,000 hours, the cost can be recovered.

In recent years, the government has also vigorously promoted high-efficiency motors, but the promotion needs to be increased. In a market economy, companies that look short-sighted are all reducing costs and purchasing, which is a contradiction to the high price of high-efficiency motors. Therefore, the promotion of high-efficiency motors also requires politicians, paying more attention to costs than focusing on efficiency, and it is difficult for high-efficiency motor benefits to be conducted to the downstream links. Therefore, the market presents the embarrassment of “being applause”. The government departments have issued mandatory policies and increased enforcement. They also need to be promoted by scientific research institutes.

In addition, relevant experts should let more consumers know how to purchase and use efficient motors.

Wu Ruiyang said that first, the overall machine must match the running speed of the motor. In general, high-efficiency motors operate at higher speeds than ordinary motors. For most turbines, their power consumption is proportional to the third power of the speed, for example, an increase of 2% in speed will result in an 8% increase in power consumption. This easily counteracts the expected savings in replacing a high-efficiency motor.

Second, select the appropriate power size motor. The efficiency of the motor remains almost constant near the rated power of 50%. If the motor power is lower than 50% of the rated power, the motor efficiency will rapidly decrease. Therefore, an oversized motor will cause significant cost increase and power factor reduction.
